Heni is a 36-year-old Hungarian production designer living in Barcelona. She has always wanted a traditional, big family, but by her mid-thirties, even though she is successful, she is still single and lonely. She decides to have a baby and as her co-parent she soon chooses Andrey – a gay Russian expat living in the same city. They will be faced with many challenges, some deriving from the cultural and age differences, but their determination to succeed as a family never fades. Cabin Pressure presents an intimate portrait of the new co-parents and their unusual family model.
